Weight In the center of the boat will just increase the volume,weight in the back will make the wake more vert but you got to keep in mind that too much weight in the back make the boat plane like crap and CAN also make the wake washy so you want to be able to plane out nicely though try to put as much weight in the back as possible without making the wake washy.Some boats if you put too much weight in the back it can make the wake soft!!

Ronai, What kind of boat? Check mine in profile...I carry 650lbs. of lead always..use fat sacs if kids want it big. I have it hidden all around the boat. In the sides, bow and behind and in the rear seat. You have to deside and try different places. Rich

a 20 foot Ski Brendella competition ski boat. Don't want to use lead because we tow the boat everywhere. My boyfriend is 6'3" and is already crammed inside the boat. I want to put some fat sacks on the side and build boxes around them. He suggests just putting a sack in the back (building a sunpad) and leaving him some legroom inside the boat. I'm starting to think his idea will actually get us a bigger wake.

I'm gonna assume it's a direct drive. 350 lbs on each side of the engine would be a very good start. That's how I would do it. I would also make sure that you got some sacks with covers so that you could walk on them.

Lead is another alternative for adding weight to your boat. The advantage with lead is obviously it's weight to volume ratio. It takes up way less room, but the bad side is that you have to tow it to and from the lake...which sucks.

what I believe is that the weight evenly distributed on the sides of the engine is going to give you the best wake. When that wake isn't big enough anymore, then put 500 in the bow, and 500 in the back.
